this one gets my award for "longest reach on a video title"
Particular ones at least. This device was new to me and a great video at that and I have 2 of its predecessors. We'll start with the older one, a Ferrania Fer-Color Mod.3
The Ferrania is a really robust contraption. You can't get the bulbs it needs any more so I had to make do with what's readily available and it's too dim to use in anything but a pitch black room. It's a pure AC device but was made for all markets, the power comes straight from the wall into a variac with an adjustment wheel. The meter you can see at the back in the second photo shows amps.
I also used to have the medium format version that did 6x6, largely the same device but with interchangeable lenses. Apparently I never took a single photo of it.
The next one is more modern and directly comparable with the ELMO TRV-35, this is a Reflecta Diamator AFM (actually an Agfa) and it hits a lot of the points the ELMO does, portable, automatic and bright enough to use in daylight.
For features it has a focus wheel, a button you press for next slide and hold for previous slide, a remote control with one button, a brightness dial that turns the lamp up or down and a slider that converts it into a regular projector you use with a screen.
It has autofocus but not how you'd first expect. When you start you adjust the manual focus dial until the picture is sharp on the screen then the autofocus measures distance to the slides surface and focuses to that, helpful if you're mixing and matching slide mounts.
The projector next to it is also an Agfa, the Diamator 1500 Autofocus from the same time period with the same feature set, and I'm pretty sure the Reflecta is just one of those in a bulky dress. The pop-up screen, hinge, and mirror and rail system take up quite a bit of real estate.
Anyway, I love projectors and messing with em. I've got a few in my collection that I take out to look at my own work and slides I collect. Here's something I made in the past using em:
These are the turn of the century version of the commercial holiday slides. These are magic lantern slides by Newton and would have been purchased in sets. The first is number 66 A Typical London Crowd and the second is number 12 of A Week in Venice.
